ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Port Adapter Overview

CHA PTER

The PA-MC-2T3+ is a single-width port adapter that provides two T3 interface connections using BNC connectors. (See Figure 1-1.) Each T3 interface can be independently configured to be either channelized or unchannelized. A channelized T3 provides 28 T1 lines multiplexed into the T3. Each T1 line can be configured into one or more serial interface data channels.

An unchannelized T3 provides a single serial interface data channel that may be configured to use all of the T3 bandwidth or a fractional portion of it. This mode is compatible with several vendors of fractional (subrate) DS3 data service units (DSUs).

The PA-MC-2T3+ has the following features and physical characteristics:

• The PA-MC-2T3+ supports both channelized and unchannelized operations.

• It transmits and receives data bidirectionally at the T3 rate of 44.736 Mbps.

• It conforms to relevant specifications for DS3 (Digital Signal Level 3) circuits.

• The T3 connection, provided by two female BNC connectors for transmit (TX) and receive (RX),

requires 734A coaxial cable that has an impedance of 75 ohms.

Channelized T3 Overview

• It supports RFC 1406 and RFC 1407 (CISCO-RFC-1407-CAPABILITY.my). For RFC 1406, Cisco

supports all tables except the FarEnd table. For RFC 1407, Cisco does not support FarEnd or Fractional tables. (For information on accessing Cisco MIB files, refer to the Cisco MIB User Quick Reference publication.)

• PA-MC-2T3+ microcode is loaded at initialization and is bundled into IOS software.

Channelized T3 Overview

In the channelized mode of operation, a PA-MC-2T3+ T3 link is channelized into 28 DS1 data lines in an industry standard multiplexing format.

Each of the T1 lines contains 24 timeslots of 64 or 56 kbps each. The T1 lines can support one or more user data channels which appear to the system as serial interfaces. Each serial interface is assigned one or more of the timeslots giving the serial interface a bandwidth of n x 56 kbps or n x 64 kbps, where n is the number of timeslots assigned. Any unused timeslots of the T1 are filled with an idle channel pattern.

The following restrictions apply: A timeslot can only be used by one serial interface. A serial interface cannot use timeslots from more than one T1 line. Each T3 can have a maximum of 128 serial interfaces. Unused serial interfaces on one T3 cannot be used by the other T3.

Chapter 1 Overview

The PA-MC-2T3+ supports Cisco High-Level Data Link Control (HDLC), Frame Relay, PPP, and Switched Multimegabit Data Service (SMDS) Data Exchange Interface (DXI) encapsulations over each serial interface.

Note T1 lines on the PA-MC-2T3+ are numbered 1–28, rather than the more traditional zero-based scheme

(0–27) used with other Cisco products. This is to ensure consistency with telco numbering schemes for T1 lines within channelized T3 equipment.

Note The PA-MC-2T3+ does not support the aggregation of multiple T1 lines (called inverse multiplexing or

bonding) in hardware for higher bandwidth data rates. MLPPP may be used for this purpose in software.

The T3 section of the PA-MC-2T3+ supports the maintenance data-link channel (MDL) when using c-bit parity framing as well as local and network loopbacks. The T1 section of the PA-MC-2T3+ supports facilities data link (FDL) in Extended Superframe (ESF) framing, as well as various loopbacks. Bit error rate testing (BERT) is supported on each of the T1 lines although a test may not be active on more than one T1 at a time. BER testing may be done over a framed or unframed T1 signal.

Unchannelized T3 Overview

In the unchannelized mode of operation, a T3 link provides a single high speed user data channel, rather than being multiplexed into 28 T1 lines. The data channel appears to the system as a serial interface that may be configured to use the full T3 bandwidth or a smaller portion of the T3 bandwidth. No industry standard exists for subdividing the T3 bandwidth but the PA-MC-2T3+ is compatible with the proprietary formats of five vendors of T3 DSUs, when used at the far end of the T3 link.

Chapter 1 Overview

In unchannelized T3 mode, the T3 section supports the maintenance data link (MDL) channel when using c-bit parity framing as well as local and network loopbacks. Bit error rate testing (BERT) is supported on the T3 link. The PA-MC-2T3+ supports Cisco High-Level Data Link Control (HDLC), Frame Relay, PPP, and Switched Multimegabit Data Service (SMDS) Data Exchange Interface (DXI) encapsulations over the serial interface.

T3 Specifications

The PA-MC-2T3+ T3 port is designed to receive and transmit at the DSX-3 level while driving and receiving from 75-ohm coaxial cables (ATT 734A or equivalent quality coax). The T3 port connects directly to any equipment with DSX-3 level BNC connectors.

Table 1 -1 lists the specifications that the T3 front end is designed to meet.

Chapter 1 Overview

Identifying Interface Addresses

This section describes how to identify interface addresses for the PA-MC-2T3+ in supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on the PA-MC-2T3+ installed in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number.

Interfaces on a PA-MC-2T3+ installed in a VIP maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP to a different slot, the interface processor slot number changes to reflect the new interface processor slot.

Note Interface ports are numbered from left to right starting with 0.

Table 1 -4 explains how to identify interface addresses.

1. Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).

2. Port adapter slot 0 can accept the Port Adapter Jacket Card if an NPE-G1 or NPE-G2 are installed.

3. Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).

Cisco 7200 Series Routers Interface Addresses

This section describes how to identify the interface addresses used for the PA-MC-2T3+ in Cisco 7200 series routers. The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Tab l e 1-4 for the interface address format.

In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. (Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present.)

The interface addresses of the interfaces on the PA-MC-2T3+ in port adapter slot 1 are 1/0 through 1/1 (port adapter slot 1 and interfaces 0 and 1). If the PA-MC-2T3+ was in port adapter slot 4, these same interfaces would be numbered 4/0 through 4/1 (port adapter slot 4 and interfaces 0 and 1).

Chapter 1 Overview

Cisco 7301 Router Interface Addresses

This section describes how to identify addresses used for the PA-MC-2T3+ in the Cisco 7301 router. In the Cisco 7301 router, slot 1 is the port adapter slot you use for the PA-MC-2T3+. (See Figure 1-5.)

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-4 on page 1-11 for the interface address format.

Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses

This section describes how to identify the interface addresses used for the PA-MC-2T3+ in the Cisco 7304 PCI Port Adapter Carrier Card in Cisco 7304 routers. The interface address is made of a two-part number in the format port-adapter-slot-number/interface-port-number.

The Cisco 7304 PCI Port Adapter Carrier Card installs into Cisco 7304 router module slots 2 through 5 (See Figure 1-7.) The port-adapter-slot-number is the Cisco 7304 router module slot number. For example, the interface address of port 0 on a PA-MC-2T3+, in which the Cisco 7304 PCI Port Adapter Carrier Card is installed in Cisco 7304 router module slot 3, would be numbered 3/0.

Cisco 7401ASR Router Interface Addresses

This section describes how to identify addresses used for the PA-MC-2T3+ in the Cisco 7401ASR router. In the Cisco 7401ASR router, slot 1 is the port adapter slot you use for the PA-MC-2T3+. (See Figure 1-8.) The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-4 on page 1-11 for the interface address format.

Chapter 1 Overview

VIP Interface Addresses

This section describes how to identify the interface addresses used for the PA-MC-2T3+ on a VIP in Cisco 7000 series and Cisco 7500 series routers.

Note Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and the 13-slot Cisco 7513 and

Cisco 7576 are vertically oriented and those in the 5-slot Cisco 7010 and Cisco 7505 are horizontally oriented, all Cisco 7000 series and Cisco 7500 series routers use the same method for slot and port numbering.

See Table 1-4 on page 1-11 for the interface address format. The interface address is composed of a three-part number in the format interface-processor-slot-number/port-adapter-slot-number/interface-port-number.

If the VIP is inserted in interface processor slot 3, then the interface addresses of the PA-MC-2T3+ are 3/1/0 through 3/1/1 (interface processor slot 3, port adapter slot 1, and interfaces 0 and 1). If the port adapter was in port adapter slot 0 on the VIP, these same interface addresses would be numbered 3/0/0 through 3/0/1.

Identifying Interface Addresses

Note If you remove the VIP with the PA-MC-2T3+ (shown in Figure 1-9 on page 1-9) from interface

processor slot 3 and install it in interface processor slot 2, the interface addresses become 2/1/0 through 2/1/1.

Checking Hardware and Software Compatibility

For configuration guidelines on port adapters in the Cisco 7200 series, refer to the Cisco 7200 Series

Port Adapter Hardware Configuration Guidelines.

Checking Hardware and Software Compatibility

To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether modules within a system are compatible, but it does provide the minimum IOS requirements for individual hardware modules or components.

Note Access to this tool is limited to users with Cisco.com login accounts.

To access Software Advisor, click Login at Cisco.com and go to Technical Support Help—Cisco TAC: Tool Index: Software Advisor. You can also access the tool by pointing your browser directly to

http://www.cisco.com/cgi-bin/support/CompNav/Index.pl.

Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware.

75-Ohm In-Line Coaxial Attenuator

A 75-ohm in-line coaxial attenuator may be required to tune the signal between the PA-MC-2T3+ and the far-end equipment, if the port adapter is experiencing line code violations (LCVs). LCVs occur when the far end equipment transmit signal saturates the front end receiver of the PA-MC-2T3+.

Cisco offers an attenuator kit (ATTEN-KIT-PA=) that contains five attenuators with fixed values ranging from 3-dB to 20-dB. For more information on the attenuator kit go to the following website:

http://www.cisco.com/univercd/cc/td/doc/product/core/7206/fru/12884att.htm

Chapter 2 Preparing for Installation

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis; do not work alone when

potentially hazardous conditions exist.

OL-3526-05

Page 39

Chapter 2 Preparing for Installation

• Never assume that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe;

carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules comprise printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• When installing a component, use any available ejector levers or captive installation screws to

properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

• When removing a component, use any available ejector levers or captive installation screws to

release the bus connectors from the backplane or midplane.

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

FCC Class A Compliance

• Place a removed board component-side-up on an antistatic surface or in a static shielding container.

If you plan to return the component to the factory, immediately place it in a static shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects

components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohms (Mohm).

FCC Class A Compliance

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.

Removing and Installing Port Adapters

This chapter describes how to remove the Cisco PA-MC-2T3+ port adapter from supported platforms and also how to install a new or replacement port adapter. This chapter contains the following sections:

• Handling Port Adapters, page 3-1

• Online Insertion and Removal, page 3-2

• Warnings and Cautions, page 3-3

• Port Adapter Removal and Installation, page 3-4

• Cables and Connectors, page 3-13

Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.

Note When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router or

switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove the blank port adapter.

Caution When powering off the router, wait a minimum of 30 seconds before powering it on again.

Handling Port Adapters

Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components

or connector pins. (See Figure 3-1 on page 3-2.)

Online Insertion and Removal

Several platforms support online insertion and removal (OIR) of port adapters; therefore, you do not have to power down routers when removing and replacing a PA-MC-2T3+ on Cisco 7100 series routers, Cisco 7200 series routers, Cisco uBR7200 series routers, Cisco 7301 routers, or Cisco 7401ASR routers.

Although the VIP and the Cisco 7304 PCI Port Adapter Carrier Card support online insertion and removal, individual port adapters do not. To replace port adapters, you must first remove the VIP or the Cisco 7304 PCI Port Adapter Carrier Card from the chassis and then install or replace port adapters as required. If a blank port adapter is installed on the VIP or the Cisco 7304 PCI Port Adapter Carrier Card on which you want to install a new port adapter, you must first remove the VIP or the Cisco 7304 PCI Port Adapter Carrier Card from the chassis and then remove the blank port adapter.

Chapter 3 Removing and Installing Port Adapters

H6420

Caution To prevent system problems, do not remove port adapters from the VIP or the Cisco 7304 PCI Port

Adapter Carrier Card motherboard or attempt to install other port adapters on the motherboard when the system is operating. To install or replace port adapters, first remove the VIP or the Cisco 7304 PCI Port Adapter Carrier Card from its interface processor slot.

It is wise to gracefully shut down the system before removing a port adapter that has active traffic moving through it. Removing a module while traffic is flowing through the ports can cause system disruption. Once the module is inserted, the ports can be brought back up.

Note Online insertion and removal (OIR) is not supported on the Port Adapter Jacket Card. OIR is supported

on the port adapter. You must have the chassis powered off to install or remove the Port Adapter Jacket Card.

Note As you disengage the module from the router or switch, online insertion and removal (OIR)

administratively shuts down all active interfaces in the module.

OIR allows you to install and replace modules while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the module you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.

Page 43

Chapter 3 Removing and Installing Port Adapters

The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a module in a supported platform, refer to the “Port Adapter

Removal and Installation” section on page 3-4.

Each module has a bus connector that connects it to the router. The connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the module. The system assesses the signals it receives and the order in which it receives them to determine if a module is being removed from or introduced to the system. From these signals, the system determines whether to reinitialize a new interface or to shut down a disconnected interface.

Specifically, when you insert a module, the longest pins make contact with the module first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a module, the pins send signals to notify the system of changes. The router then performs the following procedure:

1. Rapidly scans the system for configuration changes.

2. Initializes newly inserted port adapters or administratively shuts down any vacant interfaces.

3. Brings all previously configured interfaces on the module back to their previously installed state.

Any newly inserted interface is put in the administratively shutdown state, as if it was present (but not configured) at boot time. If a similar module type is reinserted into a slot, its ports are configured and brought online up to the port count of the originally installed module of that type.

Warnings and Cautions

Note Before you begin installation, read Chapter 2, “Preparing for Installation,” for a list of parts and tools

required for installation.

Warnings and Cautions

Observe the following warnings and cautions when installing or removing port adapters.

Note If a port adapter lever or other retaining mechanism does not move to the locked position, the port

adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot, reinsert it, and move the port adapter lever or other mechanism to the locked position.

Caution To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to

ensure that the edge connector at the rear of the port adapter mates with the connection at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in the following illustrations.

Caution When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the

card. Some platforms have an ESD connector for attaching the wrist strap.

OL-3526-05

Warning

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing.

Cisco 7200 VXR Routers Port Adapter Jacket Card

The Port Adapter Jacket Card is used in the I/O controller slot of a Cisco 7200 VXR router with either an NPE-G1 or NPE-G2 installed, and allows a port adapter to be installed in it. Both the NPE-G1 and NPE-G2 incorporate I/O controller functionality, so that with either network processing engine the I/O controller slot is available. The NPE-G1 and NPE-G2 have a third dedicated peripheral component interconnect (PCI) bus that provides additional bandwidth to the chassis. The third PCI bus allows a port adapter with a high bandwidth point requirement to be used with the Port Adapter Jacket Card in the I/O controller slot.

Note Online insertion and removal (OIR) is not supported on the Port Adapter Jacket Card. OIR is supported

on the port adapter. You must have the chassis powered off to install or remove the Port Adapter Jacket Card.

Cables and Connectors

The interface connectors on the PA-MC-2T3+ are coaxial BNC types, with one connector for transmit (TX) and one for receive (RX). The BNC connectors are transformer-coupled to the PA-MC-2T3+ line interface unit (LIU), which is the analog physical interface on the PA-MC-2T3+.

The pinout and signal descriptions for the BNC connectors on the PA-MC-2T3+ are as follows:

• Transmit (TX)—Transmitted signals appear on the center contact, and the outer shield is grounded

for the 75-ohm 734A coaxial cable you attach to the TX BNC connector.

• Receive (RX)—Received signals appear on the center contact, and the outer shield is grounded for

the 75-ohm 734A coaxial cable you attach to the RX BNC connector.

Caution To prevent problems when long cable lengths are required, you must ensure that your 75-ohm coaxial

cables meet or exceed 734A specifications. See Table 1- 1 in the “T3 Specifications” section on page 1-3 for supported cable lengths.

Figure 3-6 shows the typical 75-ohm 734A coaxial cable pair recommended for use with the

PA-MC-2T3+. Use one 75-ohm coaxial cable for each PA-MC-2T3+ connection: RX and TX.

Cables and Connectors

Note Cisco Systems does not supply cables with the PA-MC-2T3+. You must supply your own cables.

Figure 3-6 75-Ohm 734A Coaxial Cable Pair

Connecting the Cables

This section describes the procedure for attaching 75-ohm, 734A coaxial cables between the PA-MC-2T3+ port adapter and your external DS3 equipment. To continue your PA-MC-2T3+ port adapter installation, you must install the port adapter cables. The instructions that follow apply to all supported platforms.

Connect the 75-ohm coaxial cables to the PA-MC-2T3+ port adapter as follows:

Step 1 Attach the 75-ohm coaxial cables directly to the BNC ports on the PA-MC-2T3+ port adapter. Attach

one end of a cable to the port labeled TX and one end of a second cable to the port labeled RX. (See

Configuring Unchannelized mode for the Cisco PA-MC-2T3+

To continue your Cisco PA-MC-2T3+ port adapter installation, you must configure the PA-MC-2T3+ interface. The instructions that follow apply to all supported platforms. Minor differences between the platforms—with Cisco IOS software commands—are noted.

This chapter contains the following sections:

• Using the EXEC Command Interpreter, page 4-1

• Replacing an Existing Port Adapter, page 4-2

• Configuring an Unchannelized T3 Link, page 4-3

• Configuring the T3 Controller, page 4-4

• Performing a Basic Serial Interface Configuration, page 4-17

• Checking the Configuration, page 4-18

Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a

privileged-level password as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

When you enter the correct password, the system displays the privileged-level system prompt (#):

Using the EXEC Command Interpreter

Replacing an Existing Port Adapter

Before you remove or replace a port adapter, use the shutdown command to disable the port adapter to prevent anomalies when you remove and reinstall the port adapter. When you shut down an interface, it is designated administratively down in the show command displays.

Follow these steps to shut down an interface:

Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the “Using

the EXEC Command Interpreter” section on page 4-1 for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the

source of the configuration subcommands, as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Shutting Down the T3 Controller

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

Step 3 Shut down the T3 controller on the PA-MC-2T3+ with the controller command:

shutdown

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with the no shutdown controller command.

Examples follow:

• The example that follows is for a port adapter on a VIP in interface processor slot 1 of the Cisco

7500 series router:

Router(config)# controller T3 1/0/0 Router(config-controller)# shutdown

Router(config)# controller T3 1/0/1 Router(config-controller)# shutdown

• The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# shutdown

Router(config)# controller T3 1/1 Router(config-controller)# shutdown

Note Both T3 ports of the PA-MC-2T3+ should be shut down before removing the port adapter.

Step 4 Verify that the two T3 ports are now shut down using the

show controller T3 command shown in the following examples:

The following example is for a PA-MC-2T3+ in port adapter slot 6 of a Cisco 7200 series router.

Router(config-controller)# end Router# show controller T3 6/0 T3 6/0 is administratively down.

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

The following example is for a PA-MC-2T3+ in port adapter slot 1 of a VIP in a Cisco 7500 series router.

Router(config-controller)# end Router# show controller T3 1/1/0 T3 1/1/0 is administratively down.

Router# show controller T3 1/1/1 T3 1/1/1 is administratively down.

Step 5 Save the shutdown configuration to nonvolatile memory.

Router# copy running-config startup-config

Step 6 Replace the port adapter in the slot. See the “Port Adapter Removal and Installation” section on page 3-4

for more information.

Step 7 Re enable the port adapter by doing the following:

a. Repeat Step 3 to renewable an interface but substitute the no shutdown command for the shutdown

command.

b. Repeat Step 4 to verify that the interfaces are in the correct state and no longer shut down. Use the

show controller T3 command.

c. Repeat Step 5 to write the new configuration to memory.

Use the copy running-config startup-config command.

Configuring an Unchannelized T3 Link

For complete descriptions of software configuration commands, refer to the publications listed in the

“Related Documentation” section on page viii.

Configuring an Unchannelized T3 Link

If you installed a new PA-MC-2T3+ or if you want to change the configuration of an existing PA-MC-2T3+ link, you must enter the privileged level of the EXEC command interpreter and then use the configure command. If you replace a PA-MC-2T3+ that was previously configured, the system recognizes the new PA-MC-2T3+ link and brings it up in its existing configuration.

After you verify that the new PA-MC-2T3+ is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interface. Be prepared with the information you need, such as the following:

• Protocols you plan to route on each new interface

• IP addresses, if you plan to configure the interfaces for IP routing

The configure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator if necessary to obtain EXEC-level access.

Selecting a T3 Controller

You must enter the following controller command, before any other configuration commands, to select the T3 controller you want to configure:

controller T3 interface-processor-slot/port-adapter-slot/T3-port for Cisco 7500 series router

controller T3 chassis-slot/T3-port for Cisco 7200 series router

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

Setting Unchannelized Mode for the T3 Controller

To configure the T3 for unchannelized mode, use the no channelized command. After the full-rate T3 interface is configured, use the dsu bandwidth command to create a subrate T3 interface. The

following example configures a subrate T3 interface on a PA-MC-2T3+ in port adapter slot 1 of a Cisco 7200 series router.

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller t3 1/0 Router (config)# no channelized Router (config-controller)# exit Router (config)# interface serial 1/0 Router (config-if)# dsu bandwidth 16000 Router (config-if)# encapsulation frame-relay Router (config-if)# ip address 10.10.10.10 255.255.255.255 Router (config-if)# no shutdown

The following example is for a PA-MC-2T3+ in port adapter slot 1 of a VIP in a Cisco 7500 series router.

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller T3 1/1/0 Router (config)# no channelized Change to subrate mode will cause cbus complex reset. Proceed? [yes/no]: Y Router(config)# interface serial 1/1/0 Router(config-if)# encapsulation ppp Router(config-if)# ip address 10.10.10.10.10 255.255.255.255 Router(config)# no shutdown

Configuring an Unchannelized T3 Link

When the PA-MC-2T3+ is configured for unchannelized T3 mode, its default MTU size is set to 4470 for compatibility with other T3 equipment and port adapters.

Caution The change in MTU sizes will cause a memory recarve and cbus complex to occur, disrupting all traffic

on the router for several minutes. (This occurs only on Cisco 7500 series routers.)

The following message will be displayed when switching from channelized to unchannelized mode on Cisco 7500 series routers:

Change to subrate mode will cause cbus complex reset. Proceed? [yes/no]: Y

Type Y for ‘yes’ at the end of the warning. At the prompt, type ^Z to exit. This will allow you to exit configuration mode and enter unchannelized mode.

Setting the T3 port to unchannelized mode creates a serial interface which the following commands may be used to configure. Use the interface serial command to select the serial interface.

router# configure terminal router# interface serial 1/0/1 router(config-if)#

Configuring an Unchannelized T3 Link

Setting the Framing Type for the Serial Interface

In interface configuration mode, specify T3 framing by entering the {c-bit | m13} configuration subcommand, as in the following example:

router(config-if)# framing {c-bit | m13}

where:

• c-bit—C-bit parity DS3 framing

• m13—M13 Multiplex DS3 framing

Use the

no form of this command to return to the default, C-bit framing.

Specifying the Cable Length for the Serial Interface

At the prompt, specify the cable length using the interface command:

cablelength feet

where:

• feet is a numeral from 0 to 450.

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

• The default value is 10 feet.

An example follows:

Router(config-if)# cablelength 40

Note For the cablelength feet command, user-specified T3 cable lengths are structured into ranges as follows:

0–49 and 50–450 to represent short and long cables.

If the numerical value entered by the user falls within the lower range, then the PA-MC-2T3+ T3 port is set for short cable output levels. If the value falls into higher range, the long cable output levels will be used.

In the preceding example, a cable length of 40 is specified, which means that the 0–49 range is used. If you change the cable length to 45, then the 0–49 range still applies. Further, if you specify a cable length of 100 or 200, the 50–450 range applies in both cases. Only moving from one range (0–49) to the other range (50–450) has an effect. The actual cable-length number you enter is stored in the configuration file. It is recommended that the actual cable length be entered to ensure future compatibility.

Setting the Clock Source for the Serial Interface

At the prompt, set the internal or line clock source for the selected T3 controller with the interface command:

clock source {line | internal}

Where:

line—selects a network clock source

4-6

internal—selects an internal clock source

The default is clock source internal.

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

Examples follow:

• Instruct the PA-MC-2T3+ to use a line clock source.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# interface serial 1/0/0 Router(config-if)# clock source line

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# interface serial 1/0 Router(config-if)# clock source line

• Instruct the PA-MC-2T3+ to use an internal clock source.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# interface serial 1/0/0 Router(config-if)# clock source internal

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# interface serial 1/0 Router(config-if)# clock source internal

Configuring an Unchannelized T3 Link

Configuring MDL Messages for the Serial Interface

You can configure Maintenance Data Link (MDL) messages (which are defined in the ANSI T1.107a-1990 specification) on the PA-MC-2T3+.

Note MDL messages are only supported when the T3 framing is set for c-bit parity. (See the “Setting the

Framing Type for the Serial Interface” section on page 4-6.)

To configure MDL messages, use the interface commands:

mdl {transmit {path | idle-signal | test-signal} | string {eic | lic | fic | unit | pfi | port | generator}

}

string

no mdl {transmit {path | idle-signal | test-signal} | string {eic | lic | fic | unit | pfi | port |

generator} string

where:

• eic is the equipment identification code (up to 10 characters).

• lic is the location identification code (up to 11 characters).

• fic is the frame identification code (up to 10 characters).

• unit is the unit identification code (up to 6 characters).

• pfi is the facility identification code to send in the MDL path message (up to 38 characters).

• port is the equipment port, which initiates the idle signal, to send in the MDL idle signal message

(up to 38 characters).

• generator is the generator number to send in the MDL test signal message (up to 38 characters).

}

OL-3526-05

Use the no form of this command to remove MDL messages. The default is that no MDL message is configured.

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

Setting the DSU Mode for the Serial Interface

In interface configuration mode, define the DSU interoperability mode by entering the dsumode[0|1|2| 3 | 4] configuration subcommand, as in the following example:

router(config-if)# dsu mode 1

Use the no form of this command to return to the default, 0.

The local DSU mode must match the remote DSU or T3 port configuration. For example, if an ADC Kentrox DSU is at the remote end of the T3 link, then the local T3 port must be configured for mode 1.

You need to know what type of DSU is at the remote T3 end to find out if it interoperates with the PA-MC-2T3+. Specify mode 0 for connection from a PA-MC-2T3+ to another PA-MC-2T3+ or a Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-MC-2T3+ to a Kentrox DSU. Specify mode 2 for connection from a PA-MC-2T3+ to a Larscom DSU. See Table 4- 1 for a list of DSUs and their corresponding bandwidth range.

Also see the “T3 Specifications” section on page 1-3 for information regarding DSU feature compatibilities.

Note If the far end DSU has more than one DTE (HSSI) port, connect to and configure only DTE#1. See

Caution below for Verilink DSUs.

Caution Always connect to and configure HSSI port B on the Verilink HDM2182. Port A is not supported by the

PA- MC -2 T3 +.

OL-3526-05

Caution The PA-MC-2T3+ does not support the Kentrox DSU bandwidth setting of 1.0 mbps. The Kentrox DSU

speed must be set to 1.5 mbps or greater.

Caution For all DSU modes, the DSU must be configured for the same transmit and receive speeds. Asymmetrical

transmit and receive speeds are not supported.

Configuring an Unchannelized T3 Link

Setting the Bandwidth for the Serial Interface

In interface configuration mode, set the bandwidth to be used by the serial interface on the T3 link by entering the dsu bandwidth bandwidth configuration subcommand, as in the following example:

Router(config-if)# dsu bandwidth 16000

The allowable bandwidth range is 1 to 44210 kbps. Use the no form of this command to return to the default, 44210.

The local DSU bandwidth value must match the remote DSU or T3 port bandwidth exactly. For example, if you set the DSU bandwidth to 16000 on the local port, you must do the same on the remote DSU or T3 port.

Setting Scrambling for the Serial Interface

In interface configuration mode, enable serial interface scrambling by entering the scramble configuration subcommand, as in the following example:

router(config-if)# scramble

Use the no form of this command to restore the default value, disabled.

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

The local port configuration must match the remote DSU or T3 port configuration. For example, if you enable scrambling on the local port, you must do the same on the remote DSU or T3 port.

Configuring Loopback Mode for the Serial Interface

With loopbacks, you can detect and isolate equipment malfunctions by testing the connection between the PA-MC-2T3+ interface and a remote device such as a CSU/DSU. Remote loopback sends a command to loop the T3 line at the far end. It can be used to diagnose problems with cables from the port adapter to the switching office. Network loopback loops the PA-MC-2T3+ T3 port back to the network, allowing the remote end to test the connection to the PA-MC-2T3+.

Local loopback loops the PA-MC-2T3+ T3 port back to itself allowing it to be tested in isolation from the T3 cables and remote T3 equipment.

The loopback subcommand places an interface in loopback mode, which enables test packets that are generated from the ping command to loop through a remote device and cables. If the packets complete the loop, the connection is good.

Table 4 -2 provides examples of the loopback {local | network {line | payload} | remote {line | payload}

command. You can configure the serial interface for loopback modes using the interface command:

loopback [local | network | remote]

The default is no loopback.

To return the serial interface to its default unlooped condition, use the no form of the command.

Table 4-2 Using loopback Commands

Configuring an Unchannelized T3 Link

loopback local Sets the interface into local loopback

mode. Local loopback loops the router output data back toward the router at the

Router(config)# interface serial 10/0/0 router(config-if)# loopback local

framer.

loopback network line Sets the interface into network line

loopback mode. Network line loopback loops the data back toward the network (before the framer).

loopback network payload Sets the interface into network payload

loopback mode. Network payload loopback loops just the payload data back toward the network at the T3 framer.

loopback remote

Sends a command to the remote T3 device instructing it to loop itself back toward the network (before the framer at the

Router(config)# interface serial 10/0/0 router(config-if)# loopback network line

Router(config)# interface serial 10/0/0 router(config-if)# loopback network payload

Router(config)# interface serial 10/0/0 router(config-if)# loopback remote

remote T3 device).

loopback remote line

Sends a command to the remote Kentrox to loop itself back toward the network before the framer.

loopback remote payload

Sends a command to the remote Kentrox DSU to loop only the payload after the framer back toward the network.

1. Remote loopback mode works with C-bit framing only. The other loopback modes listed above work with C-bit and M13 framing. Refer to the “Setting

the Framing Type for the Serial Interface” section on page 4-6 for information on configuring C-bit framing.

2. These loopback commands are only available when the DSU mode is set to 1, Kentrox mode.

Router(config)# interface serial 10/0/0 router(config-if)# loopback remote line

Router(config)# interface serial 10/0/0 router(config-if)# loopback remote payload

Configuring the T3 controller to Enable Loopbacks

The PA-MC-2T3+ can be configured to respond to or to ignore remote T3 loopback requests sent to it from the far end T3 equipment. Equipment customer loopback enables the port adapter to respond to remote T3 loopback commands from the remote T3 equipment while equipment network loopback causes the PA to ignore remote T3 loopback commands.

equipment [customer | network] loopback

Router(config)# controller T3 1/0 Router(config-controller)# equipment customer loopback

Note Remote loopbacks are only available when you use c-bit parity framing.

Shutting Down the T3 Controller

You can shut down the T3 controller on the PA-MC-2T3+ with the controller command:

shutdown

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with the no shutdown controller command.

Examples follow:

• The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# shutdown

• The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# shutdown

Configuring a BER Test on the T3 Controller

Bit error rate test (BERT) circuitry is built into the PA-MC-2T3+. With BER tests, you can test cable and signal problems in the field.

There are two categories of test patterns that can be generated by the onboard BER test circuitry: pseudorandom and repetitive. The former test patterns are polynomial based numbers and conform to the CCITT/ITU O.151 and O.153 specifications; the latter test patterns are zeros or ones, or alternating zeros and ones.

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

A list of the available test patterns follows:

• Pseudorandom test patterns:

–

2^15 (per CCITT/ITU O.151)

–

2^20 (per CCITT/ITU O.151 non-QRSS)

–

2^23 (per CCITT/ITU O.151)

• Repetitive test patterns:

–

All zeros (0s)

–

All ones (1s)

–

Alternating zeros (0s) and ones (1s)

Both the total number of error bits received and the total number of bits received are available for analysis. You can set the testing period from 1 minute to 14,400 minutes (240 hours), and you can also retrieve the error statistics anytime during the BER test.

When running a BER test, your system expects to receive the same pattern that it is transmitting. To accomplish this, two common options are available:

• Use a loopback somewhere in the link or network.

• Configure remote testing equipment to transmit the same BER test pattern at the same time.

–

2^23, pseudorandom O.151 test pattern (8,388,607 bits long)

–

alt-0-1, repetitive alternating test pattern of zeros (0s) and ones (1s), (as 01010101)

• time is 1–14400 minutes.

Examples follow:

• Send a BERT pseudorandom pattern of 2^23 for 5 minutes.

Configuring an Unchannelized T3 Link

The example that follows is for a port adapter on a VIP in interface processor slot 1:

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# bert pattern 2^23 interval 5

• Send a repetitive pattern of all ones for 14400 minutes (240 hours).

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# bert pattern 1s interval 14400

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# bert pattern 1s interval 14400

Note You can terminate a BER test during the specified test period with the no bert command.

Configuring an Unchannelized T3 Link

Test Pattern : All 1's, Status : Sync, Sync Detected : 1 Interval : 14400 minute(s), Time Remain : 14400 minute(s) Bit Errors (since BERT started): 0 bits, Bits Received (since BERT started): 92 Mbits Bit Errors (since last sync): 0 bits Bits Received (since last sync): 92 Mbits

The following explains the output of the preceding command, line by line:

Output Display Line Explanation

BERT test result (running)

This line indicates the current state of the test. In this case, “running” indicates that the BER test is still in process. After a test is completed, “done” is displayed.

Test Pattern : 2^15, Status : Sync, Sync Detected : 1

This line indicates the test pattern you selected for the test (2^15), the current synchronization state (sync), and the number of times synchronization has been detected during this test (1).

Interval : 5 minute(s), Time Remain : 5 minute(s)

This line indicates the time the test takes to run and the time remaining for the test to run.

Interval : 5 minute(s), Time Remain : 2 minute(s) (unable to complete)

For a BER test that you terminate, this line indicates the time the test would have taken to run and the time remaining for the test to run had you not terminated it; “unable to complete” signifies that you interrupted the test.

Bit Errors(Since BERT Started): 6 bits,

Bits Received(Since BERT start): 8113 Kbits

Bit Errors(Since last sync): 6 bits

Bits Received(Since last sync): 8113 Kbits

These four lines show the bit errors that have been detected versus the total number of test bits that have been received since the test started and since the last synchronization was detected. Bits and errors are only counted when the test status is “sync”.

Terminating a BER Test

You can terminate a BER test with the controller command:

no bert

Examples follow:

Terminate the BER test running on T3 0.

• The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# no bert

• The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# no bert

To check your configurations using show commands, proceed to the “Checking the Configuration”

section on page 4-18; otherwise, proceed to the following section to perform a basic interface

configuration.

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

Performing a Basic Serial Interface Configuration

Following are instructions for a basic configuration: enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. For complete descriptions of configuration subcommands and the configuration options available for serial interfaces, refer to the appropriate software documentation.

In the following procedure, press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:

Router# disable

Router>

Step 1 Enter configuration mode and specify that the console terminal is the source of the configuration

subcommands, as follows:

Router# configuration terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Configuring an Unchannelized T3 Link

Step 2 Specify the first interface to configure by entering the interface serial subcommand, followed by the

interface address of the interface you plan to configure. See “Port Adapter Slot Locations on the

Supported Platforms” section on page 1-5 and “Identifying Interface Addresses” section on page 1-11.

This example is for the serial interface of T3 port 0 in port adapter slot 6.

Router(config)# interface serial 6/0 Router(config-if)#

This example is for the serial interface of T3 port 0 of a port adapter in port adapter slot 1 of a VIP in interface processor slot 2.

Router(config)# interface serial 2/1/0

Router(config-if)#

Step 3 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using

the ip address subcommand, as in the following example:

Router(config-if)# ip address 10.0.0.0 10.255.255.255

Step 4 Add any additional configuration subcommands required to enable routing protocols and set the

interface characteristics.

Step 5 Re enable the interfaces using the no shutdown command. (See the “Replacing an Existing Port

Adapter” section on page 4-2.)

Step 6 Configure all additional port adapter interfaces as required. Step 7 After including all of the configuration subcommands to complete your configuration, press

Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Step 8 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config [OK] Router#

Checking the Configuration

This completes the procedure for creating a basic configuration.

Checking the Configuration

After configuring the new interface, use the show commands to display the status of the new interface or all interfaces, and use the ping and loopback commands to check connectivity. This section includes the following subsections:

• Using show Commands to Verify the New Interface Status, page 4-18

• Using the ping Command to Verify Network Connectivity, page 4-30

• Using loopback Commands to Troubleshoot Network Problems, page 4-30

Using show Commands to Verify the New Interface Status

Table 4 -3 demonstrates how you can use the show commands to verify that new interfaces are configured

and operating correctly and that the PA-MC-2T3+ appears in them correctly. Sample displays of the output of selected show commands appear in the sections that follow. For complete command descriptions and examples, refer to the publications listed in the “Related Documentation” section on

page viii.

Checking the Configuration

Using the show controllers Command

You can display information for the T3 controller within a PA-MC-2T3+ in Cisco 7200 series, Cisco 7301 routers, and Cisco 7401ASR routers with the command:

show controllers t3 port-adapter/t3-port [brief | tabular]

where:

• brief displays a list of configurations only.

• tabular displays a list of configurations and MIB data in a tabular format.

Note If you use the show controllers t3 port-adapter/port command without either of the optional arguments

(brief or tabular), all information is displayed for the T3 controller you specified; therefore, the resulting display output can be extensive.

Note You can use these show controllers t3 commands for Cisco 7500 series routers in which the

PA-MC-2T3+ is supported. The syntax is as follows:

— show controllers t3 slot/port-adapter/t3-port brief

— show controllers t3 slot/port-adapter/t3-port tabular

(additional displayed text not shown)

If you use the show controllers T3 command without specifying a port address (slot/port-adapter/port), all information is displayed for all T3 port adapters in the router; therefore, the resulting display output can be extensive.

Using the ping Command to Verify Network Connectivity

Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the “Related

Documentation” section on page viii for detailed command descriptions and examples.

The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!)

indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a

bad connection.

Following is an example of a successful ping command to a remote server with the address 10.0.0.10:

Router# ping 10.0.0.10 <Return> Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms Router#

If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.

Proceed to the next section, “Using loopback Commands to Troubleshoot Network Problems,” to finish checking network connectivity.

Using loopback Commands to Troubleshoot Network Problems

4-30

If you have difficulty with the PA-MC-2T3+ configuration or installation, you can troubleshoot the port adapter using the loopback command. Refer to the “Configuring Loopback Mode for the Serial

Interface” section on page 4-10 for instructions on setting loopbacks.

PA-MC-2T3+ Multi-Channel T3 Port Adapter Installation and Configuration

OL-3526-05

Page 85

Chapter 4 Configuring Unchannelized mode for the Cisco PA-MC-2T3+

If the ping command to the remote IP address failed, then use loopbacks to troubleshoot the T3 connection using the following steps:

Step 1 Use the show controller T3 and show interface serial commands to confirm that the T3 controller,

serial interface, and line protocol are up.

Step 2 Place the serial interface of the PA-MC-2T3+ in local loopback using the loop local command. Step 3 Repeat the ping command using the IP address of the local serial interface. Using the previous example

where the remote server’s IP address was 10.0.0.10, if the local IP address is 10.0.0.5, then use the command:

ping 10.0.0.5

If the ping is successful, proceed to Step 4. A failure indicates a configuration problem or a hardware problem with the PA-MC-2T3+.

Step 4 Remove the local loop with the no loopback command and place the remote server or DSU in network

loopback with the loopback remote command.

Note The loopback remote command is only available when the framing is set to c-bit parity. If the framing

is not set to c-bit parity, the remote server will have to be placed into network loopback by someone at the remote site.

Checking the Configuration

Step 5 Repeat Step 3. If the ping is successful then the PA-MC-2T3+ and the T3 link to the remote site is

functioning correctly. The problem is probably in the remote DSU or server configuration or hardware. If the ping fails then either the T3 link to the remote site or the remote server or DSU configuration or hardware has a problem.

Using the EXEC Command Interpreter

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a

privileged-level password as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

When you enter the correct password, the system displays the privileged-level system prompt (#):

Using the EXEC Command Interpreter

Replacing an Existing Port Adapter

Follow these steps to shut down an interface:

Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the “Using

the EXEC Command Interpreter” section on page 5-1 for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the

source of the configuration subcommands, as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Shutting Down the T3 Controller

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

Step 3 Shut down the T3 controller on the PA-MC-2T3+ with the controller command:

shutdown

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with the no shutdown controller command.

Examples follow:

• The example that follows is for a port adapter on a VIP in interface processor slot 1 of the Cisco

7500 series router:

Router(config)# controller T3 1/0/0 Router(config-controller)# shutdown

Router(config)# controller T3 1/0/1 Router(config-controller)# shutdown

• The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# shutdown

Router(config)# controller T3 1/1 Router(config-controller)# shutdown

Note Both T3 ports of the PA-MC-2T3+ should be shut down before removing the port adapter.

Step 4 Verify that the two T3 ports are now shut down using the

show controller T3 command shown in the following examples:

The following example is for a PA-MC-2T3+ in port adapter slot 6 of a Cisco 7200 series router.

Router(config-controller)# end Router# show controller T3 6/0 T3 6/0 is administratively down.

Router# show controller T3 1/1/1 T3 1/1/1 is administratively down.

Step 5 Save the shutdown configuration to nonvolatile memory.

Router# copy running-config startup-config

Step 6 Replace the port adapter in the slot. See the “Port Adapter Removal and Installation” section on page 3-4

for more information.

Step 7 Reenable the port adapter by doing the following:

a. Repeat Step 3 to reenable an interface but substitute the no shutdown command for the shutdown

command.

b. Repeat Step 4 to verify that the interfaces are in the correct state and no longer shut down. Use the

show controller T3 command.

c. Repeat Step 5 to write the new configuration to memory.

Use the copy running-config startup-config command.

Configuring a Channelized T3 Link

“Related Documentation” section on page viii.

Configuring a Channelized T3 Link

• Protocols you plan to route on each new interface

• IP addresses, if you plan to configure the interfaces for IP routing

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

Selecting a T3 Controller

You must enter the following controller command, before any other configuration commands, to select the T3 controller you want to configure:

controller T3 interface-processor-slot/port-adapter-slot/T3-port for Cisco 7500 series router

controller T3 chassis-slot/T3-port for Cisco 7301 router\

controller T3 chassis-slot/T3-port for Cisco 7401ASR router

controller T3 chassis-slot/T3-port for Cisco 7200 series router

Examples of selecting the T3 controller follow:

• The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller t3 1/0/0 Router(config-controller)#

• The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller t3 1/0 Router(config-controller)#

Setting Channelized Mode for the T3 Controller

Note Channelized mode is the default, so you only need to configure the T3 for channelized mode if it had

previously been set to ‘no channelized’ mode.

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

To configure the T3 for channelized mode, use the channelized command. The following example is for a PA-MC-2T3+ in port adapter slot 1 of a Cisco 7200 series router.

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller T3 1/0 Router (config)# channelized

The following example is for a PA-MC-2T3+ in port adapter slot 1 of a VIP in a Cisco 7500 series router.

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller T3 1/1/0 Router (config)# channelized

Change to channelized mode will cause cbus complex reset. Proceed? [yes/no]:

When the PA-MC-2T3+ is configured for channelized T3 mode, its default MTU size is set to 1500 for compatibility with other T3 equipment and port adapters.

When the T3 controller is configured to be channelized, 28 T1 lines are created. To configure the T1 lines, refer to the “Configuring T1 Lines” section on page 5-10.

Configuring a Channelized T3 Link

Caution The change in MTU sizes will cause a memory recarve and cbus complex to occur, disrupting all traffic

on the router for several minutes. (This occurs only on Cisco 7500 series routers.)

The following message will be displayed when switching from unchannelized to channelized mode on Cisco 7500 series routers:

Change to channelized mode will cause cbus complex reset. Proceed? [yes/no]:

Type Y for ‘yes’ at the end of the warning. At the prompt, type ^Z to exit. This will allow you to exit configuration mode and enter channelized mode.

Setting the Framing Type for the T3 Controller

At the prompt, specify the framing type using the controller command:

framing [c-bit | m23 | auto-detect]

You can set c-bit framing format as follows:

Router(config-controller)# framing c-bit

You can set m23 framing format as follows:

Router(config-controller)# framing m23

You can request the PA-MC-2T3+ to detect the framing type it is receiving from the far end and transmit that same framing type as follows:

Router(config-controller)# framing auto-detect

Specifying the Cable Length for the T3 Controller

At the prompt, specify the cable length using the controller command:

cablelength feet

where:

• feet is a numeral from 0 to 450.

• The default value is 49 feet.

An example follows:

Router(config-controller)# cablelength 40

Note For the cablelength feet command, user-specified T3 cable lengths are structured into ranges as follows:

0–49 and 50–450 to represent short and long cables.

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

Setting the Clock Source for the T3 Controller

At the prompt, set the internal or line clock source for the selected T3 controller with the controller command:

clock source {internal | line}

The default is clock source internal.

Examples follow:

• Instruct the PA-MC-2T3+ to use a line clock source.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# clock source line

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# clock source line

5-6

• Instruct the PA-MC-2T3+ to use an internal clock source.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# clock source internal

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# clock source internal

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

Configuring MDL Messages for the T3 Controller

You can configure Maintenance Data Link (MDL) messages (which are defined in the ANSI T1.107a-1990 specification) on the PA-MC-2T3+.

Note MDL messages are only supported when the T3 framing is set for c-bit parity. (See the “Setting the

Framing Type for the T3 Controller” section on page 5-5.)

To configure MDL messages, use the controller commands:

mdl {transmit {path | idle-signal | test-signal} | string {eic | lic | fic | unit | pfi | port | generator}

string

}

no mdl {transmit {path | idle-signal | test-signal} | string {eic | lic | fic | unit | pfi | port |

generator} string

where:

• eic is the equipment identification code (up to 10 characters).

}

Configuring a Channelized T3 Link

• lic is the location identification code (up to 11 characters).

• fic is the frame identification code (up to 10 characters).

• unit is the unit identification code (up to 6 characters).

• pfi is the facility identification code to send in the MDL path message (up to 38 characters).

• port is the equipment port, which initiates the idle signal, to send in the MDL idle signal message

(up to 38 characters).

• generator is the generator number to send in the MDL test signal message (up to 38 characters).

Use the no form of this command to remove MDL messages. The default is that no MDL message is configured.

Examples of MDL Message Configuration

Examples of configuring MDL messages follow:

• Enter controller configuration mode first.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router# configure t Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller T3 1/0/0 Router(config-controller)#

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router# configure t Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller T3 1/0 Router(config-controller)#

OL-3526-05

• Enable the MDL path message transmission as follows:

Router(config-controller)# mdl transmit path

• Enable the MDL idle signal message transmission as follows:

Router(config-controller)# mdl string port string

• Enter the generator number to send in the MDL test signal message as follows:

Router(config-controller)# mdl string generator string

Configuring the Loopback Mode for the T3 Controller

With loopbacks, you can detect and isolate equipment malfunctions by testing the connection between the PA- T3 + interface and the remote T3 device such as a DS3 MUX. Remote loopback sends a command to loop the T3 line at the far end (central office). It can be used to diagnose problems with cables from the port adapter to the switching office. Network loopback loops the PA-MC-2T3+ T3 port back to the network allowing the remote end to test the connection to the PA-MC-2T3+. Local loopback loops the PA-MC-2T3+ T3 port output back to itself allowing it to be tested in isolation from the T3 cables and remote T3 equipment.

You can configure the T3 controller for loopback modes using the controller command:

loopback [local | network | remote]

The default is no loopback.

5-8

To return the T3 controller to its default unlooped condition, use the no form of the command.

Table 5 -1 provides examples of the loopback {local | network | remote} command.

OL-3526-05

Page 95

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

Table 5-1 Using loopback commands

Configuring a Channelized T3 Link

loopback local Sets the T3 port into local loopback

mode. Local loopback loops the router output data back toward the router at the

Router(config)# controller T3 10/0/0 router(config-controller)# loopback

local

framer.

loopback network Sets the T3 port into network line

loopback mode. Network line loopback loops the data back toward the network

Router(config)# controller t3 10/0/0 router(config-controller)# loopback

network line

(before the framer).

loopback remote

Sends a command to the remote T3 device instructing it to loop itself back to the network (before the framer at the remote

Router(config)# controller T310/0/0 router(config-controller)# loopback

remote

T3 device).

1. Remote loopback mode works with C-bit framing only. The other loopback modes listed above work with C-bit, and M23. Refer to the “Setting the

Framing Type for the T3 Controller” section on page 5-5 for information on configuring C-bit framing.

Configuring the T3 controller to Enable Remote Loopback

Equipment customer loopback enables the PA-MC-2T3+ port adapter to respond to remote T3 loopback and T1 loopback requests it receives from the remote site, while equipment network

loopback causes the PA to ignore remote T3 and T1 loopback commands.

equipment [customer | network] loopback

router(config)# controller T3 3/0 router(config-controller)# equipment customer loopback

router(config)# controller T3 3/0 router(config-controller)# equipment network loopback

Note T3 remote loopbacks are only available when you use c-bit parity framing.

Shutting Down the T3 Controller

You can shut down the T3 controller on the PA-MC-2T3+ with the controller command:

shutdown

This command sends a DS3 idle signal toward the network. You can bring the T3 controller back up with the no shutdown controller command.

Examples follow:

• The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller t3 1/0/0 Router(config-controller)# shutdown

• The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller t3 1/0 Router(config-controller)# shutdown

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

Note For consistency throughout the following configuration examples and whenever possible, the port

addresses 1/0/0 and 1/0/0/1:1 are used for Cisco 7500 series routers and 1/0 and 1/0/1:1 for Cisco 7200 series routers.

Your PA-MC-2T3+ port addressing might be different depending on the Cisco 7200 series router chassis slot or the interface processor slot in which your VIP is installed and the VIP port adapter slot in which your PA-MC-2T3+ is installed.

Creating a Logical Channel Group on a T1 Line

You can create a logical channel group on a T1 line using the following controller command:

t1 t1-line-number channel-group channel-group-number timeslots list-of-timeslots [speed {56 | 64}]

where:

• t1-line-number is 1–28.

• channel-group defines a logical channel group.

• channel-group-number is 0–23.

• timeslots list-of-timeslots can be 1–24 or a combination of subranges within 1–24 (each subrange

is a list of timeslots of the T1 line).

• speed{56 | 64} is an optional argument that specifies the speed of a time slot to be either 56 kbps or

64 kbps.

Configure logical channel group 20 on T1 line 1 and assign channelized timeslots 1 to 5 and 20 to 23.

5-10

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# t1 1 channel-group 20 timeslots 1-5, 20-23

PA-MC-2T3+ Multi-Channel T3 Port Adapter Installation and Configuration

OL-3526-05

Page 97

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# t1 1 channel-group 20 timeslots 1-5, 20-23

Note Each T1 link may have up to 24 channel groups with an overall limit of 128 for the 28 T1 links on each

T3 port. Unused channel groups in one T3 port may not be used by the other T3 port.

Note Each channel group defined with this command causes a serial interface to be created. Refer to the

“Performing a Basic Serial Interface Configuration” section on page 5-24 for instructions on configuring

these interfaces.

Note All the encapsulation formats, such as PPP, HDLC, SMDS, Frame Relay, and switching types are

applicable to the serial interface and can be set using the serial interface configuration commands.

Removing a Logical Channel Group from a T1 Line

Configuring a Channelized T3 Link

You can remove a logical channel group from a T1 line with the following controller command:

no t1 t1-line-number channel-group channel-group-number

where:

• t1-line-number is 1–28.

• channel-group-number is 0–23.

Remove logical channel group 10 from channelized T1 line 1.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# no t1 1 channel-group 10

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# no t1 1 channel-group 10

Note If logical channel groups had previously been configured on a port, and you switch to ‘no channelized’

mode, first remove all channel groups before invoking the ‘no channelized’ command.

Setting the Framing Format on a T1 Line

You can specify the T1 framing format using the controller command:

OL-3526-05

t1 t1-line-number framing {esf | sf}

where:

• The default framing format is extended super frame (ESF).

• t1-line-number is 1–28.

Examples follow:

• Set Super Frame (SF) framing format for T1 line 6.

PA-MC-2T3+ Multi-Channel T3 Port Adapter Installation and Configuration

5-11

Page 98

Configuring a Channelized T3 Link

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# t1 6 framing sf

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# t1 6 framing sf

• Other options for setting Super Frame (SF) include:

router(config-controller)#t1 6 framing ? esf Extended Superframe Framing format sf Superframe Framing Format

router(config-controller)#t1 6 framing sf ? hdlc-idle Specify the HDLC idle pattern on a T1 <cr>

router(config-controller)#t1 6 framing sf hdlc-idle ? 0x7E Use 0x7E as HDLC idle pattern 0xFF Use 0xFF as HDLC idle pattern

router(config-controller)#t1 6 framing sf hdlc-idle 0x7e ?

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

• Set ESF framing format for T1 line 16 as follows:

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# t1 16 framing esf

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# t1 16 framing esf

Note Use of the 0xFF HDLC idle pattern may help prevent false yellow alarms in the remote T1 device when

SF framing is used.

Setting the Yellow Alarm Configuration for a T1 Line

You can use the [no] t1 t1-line-number yellow {detection | generation} command (where t1-line-number is 1–28) to turn the detection or generation of a yellow alarm on and off. When you select

SF framing, you should consider using the no t1-line-number yellow detection command to turn off yellow alarm detection, because the yellow alarm can be incorrectly detected with SF framing.

Setting the Clock Source on a T1 Line

You can set the internal or line (network) clock source for a T1 line with the controller command:

t1 t1-line-number clock source {internal | line}

5-12

where:

• t1-line-number is 1–28.

• The default clock source is internal.

Examples follow:

PA-MC-2T3+ Multi-Channel T3 Port Adapter Installation and Configuration

OL-3526-05

Page 99

Chapter 5 Configuring Channelized mode for the Cisco PA-MC-2T3+

• Instruct T1 line 1 to use an internal clock source.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# t1 1 clock source internal

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# t1 1 clock source internal

• Instruct T1 line 16 to use a line clock source received from the network.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router(config)# controller T3 1/0/0 Router(config-controller)# t1 16 clock source line

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router(config)# controller T3 1/0 Router(config-controller)# t1 16 clock source line

Note Normally the T1 link should be configured to use the line clock recovered from the network. In cases

where the network does not provide the clock, such as two PA-MC-2T3+ port adapters connected back-to-back, one end of the T1 link must be set to internal clock and the other end to line clock.

Configuring a Channelized T3 Link

Setting the FDL Configuration for a T1 Line

To enable and disable 1-second transmissions of performance reports through the facility data link (per ANSI T1.403 specification), you must use the following command on both ends of the connection:

t1 t1-line-number fdl ansi

where: t1-line-number is 1–28.

Note You can use this command only when the T1 framing is ESF. Use the no form of the command to disable

remote performance reports.

Setting Loopbacks on a T1 Line

If you have difficulty with the PA-MC-2T3+ configuration or installation, you can troubleshoot the port adapter using the loopback command. Specify loopback for a T1 line using the following command:

t1 t1-line-number loopback [local | network | remote]

where: t1-line-number is 1–28.

Note This command requires that you are in T3 controller mode.

OL-3526-05

Note fdl loopback commands are available only for T1 lines configured for ESF framing.

Explanations of specific loopback modes follow:

11111111) to the remote end, requesting that it enter into a network payload loopback. Enables the remote payload Facility Data Link (FDL) ANSI loopback on the T1 channel.

You can optionally specify fdl and ansi, but it is not necessary.

Examples of the loopback commands follow:

• Set the first T1 line into local loopback.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller T3 1/0/0 Router(config-controller)# t1 1 loopback local

The example that follows is for a port adapter in slot 1 of the Cisco 7200 series routers:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# controller T3 1/0 Router(config-controller)# t1 1 loopback local

In the preceding examples, local loopback loops the router output data back toward the router at the T1 framer and sends an AIS out toward the network.

• Set the first T1 line into network line loopback.

The example that follows is for a port adapter on a VIP in interface processor slot 1:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z.
